Goulds Model 3910 for Refinery Services

The 3910 offers inherent in-line advantages:

Lower Installation Costs No heavy foundationrequired.

Minimum Floorspace Ideal for retrofitting anddebottlenecking.

Shaft-to-Shaft Alignment Maintained during

changes in nozzle loads or operating conditions(thermal cycling).

In-Line Suction and Discharge Simplifiespiping design and construction. Goulds 3910 isdesigned to meet the demandingrequirements of the HydrocarbonProcessing Industries.

3910 Bearing Frame Design for Reliability

Goulds Model 3910 combines in-line and horizontal

pump advantages...

Positive Shaft Alignment Extended seal andbearing life and reduced vibration.

Proven Shaft Stiffness Reduced deflection forextended seal life.

Standard Mechanical Seals

Standard Flexible Couplings

Simplified Maintenance Use of GouldsFramehook allows safe and easy maintenance.

Standard Vertical Motors Powerend absorbs all pump hydraulic loads.

Bearing Frame Design Eliminates Rigid Coupled In-Line

Problems:

Eliminates product lubricatedbushings that wear and increaseshaft deflection.

Complex rigid coupling assemblyand shaft alignment proceduresnot required.

Special motor designs not required.

Goulds 3910 is designed to meet the demanding requirements of theHydrocarbon Processing Industries.

Parts Availability

Goulds Distribution Centers are

strategically located worldwide, andare committed to the ready availability

of repair parts.

Goulds Value Added Service

Now theres a safe and easy way to remove the back pull-outassembly for offsite maintenance... without removing the

motor or disturbing suction and discharge piping.

Goulds Framehook facilitates removal (and installation)

of the back pull-out. Maintenance personnel can now

remove a heavy assembly safely and in minimum time.

After removing the casing stud nuts, coupling spacer and

any flush or seal piping, position Framehook using

suitable lifting capability.

With Framehook bolted in place, separate the assembly

from the casing by using the jacking bolts.

Lift assembly clear of casing studs.

Tilt the unit using threaded adjustment rod for easy

removal through opening in motor support.

The entire back pull-out assembly ready for offsite

maintenance.

Design Features forOptimum Reliability

Goulds Model 3910 utilizes proven designfeatures to ensure reliable performance.

High Temperature CapabilityFor high temperature applications, these options are available.

Rotating Element

Shaft and bearings are same as used with Goulds Model

3700 horizontal process pump. Proven

design preferred for toughest services.

Engineered in-line Suction Design

The 3910 suction design is the result of extensive model

and full-scale testing. NPSH requirements are minimized.

Design assures streamlined, even flow into impeller eye;

reduces losses encountered in conventional suction

designs.

Heat Flinger and Thermal Barrier

Thermal gasket creates heat barrier between

seal chamber and bearing frame. Heat

flinger dissipates shaft-conducted heat andcirculates air to reduce heat build-up.

Air Cooling

High capacity fan and shroud mounted

on power end effectively reduce bearing

frame temperature for cooler running

bearings without using cooling water.

Not All Pumps are Designed for Low Flows

Many users throttle pumps to attain low flow rates - yet

create bearing and seal issues. The traditional enclosed

impeller passage ways would be too small to properly

manufacture at these low flow rates.

3910LF Low Flow Solution - Fully API compliant

The 3910LF semi-open radial vane Barske type impeller

eliminates these enclosed impeller limitations. The uniquecircular volute casing eliminates competitor diffusers thus

reducing the pump size, footprint and lifetime costs.

Optional 3910LF Design for Low-Flow Services


6/12

SPACER COUPLING

With standard spacer length used for all applications.

PUMP BEARINGS

Carry all pump hydraulic loads.

Duplex angular contact thrust bearings and deepgroove Conrad radial bearing standard with grease

lubrication. Oil mist optional.

MODEL 3700 INTERCHANGEABILITY

Bearing frame, bearings, shaft, seal chamber,mechanical seal, impeller and wear rings completelyinterchangeable with Goulds Model 3700 horizontal

process pumps.

BACK PULL-OUT

Frame assembly, cover, impeller easily removed as a unit

for maintenance using Goulds patented FRAMEHOOKTM

without disturbing piping or motor.

SEAL CHAMBER COVER

Conforms fully to API-610/ISO 13709. Designed to

accept wide range of API 682/ISO 21049 cartridge seals.

IMPELLER

Impeller balanced to stingent ISO 1940 Grade 1.0(exceeds API minimum). 3910LF low flow pumps utilizea semi-open impeller, they do not utilize impeller or

casing wear rings.

OPTIONAL CASING SUPPORTS

Provide additional support and stability. One piecefabricated support available.

STANDARD C-FACE VERTICAL MOTOR

Does not require special thrust bearings to carry

pump loads. Other motor designs can be used.

HEAVY DUTY BEARING FRAME

Rabbeted fits assure runout and concentricity withinAPI-610/SO 13709 specifications. Accessible monitoringlocations. Frame machined for use of Goulds

FRAMEHOOKTM back pull-out removal device.

RIGID MOTOR SUPPORT

Maintains alignment between pump and motor. Open

on both sides for ventilation, ease of maintenance.

RIGID SHAFT ASSEMBLY

Limits deflection at seal faces to less than 0.002 in. (.05

mm) under the most severe operating conditions.IN-LINE DESIGN

Simplifies installation, minimizes floor space requirements.

IN-LINE CASING

Rugged design, accepts two times API-610/ISO 13709

nozzle loads. 300 RF flanges standard. Proprietary suction

design assures smooth, even flow into impeller eye.
